Qantas passengers on domestic flights will soon be able to board with heavier carry-on luggage.

From March 25, customers will be allowed to bring on board a bag weighing 10kg – up from 7kg – plus a second bag and a personal item.

The total baggage weight will remain at 14kg per person, all that has changed is the maximum weight of one of the items.

The size limits on cabin bags will remain the same, while customers can still bring one small personal item in addition to two pieces of luggage.

Luggage weighing over 10kg will have to be checked in.

The change follows feedback from hundreds of passengers – including frequent flyers - who said the 7kg limit was too difficult to stick to.

“Qantas offers the most generous amount of cabin baggage of any Australian airline and we know a lot of customers like the convenience of not having to check in luggage,” Qantas Domestic CEO Andrew David said in a statement.

“Most customers on short business trips and weekends away only travel with one carry-on bag plus a small personal item.

“We’ve had feedback from our frequent flyers who said they can easily keep within the 14kg limit but would like flexibility in how they use their cabin baggage allowance.”
